Apple seemingly had large plans, including ray tracing support, for the A16 Bionic's GPU successful the iPhone 14 Pro but had to revert to a plan based connected the erstwhile A15 Bionic. This was owed to a large powerfulness depletion flaw discovered precocious successful the SoC's improvement cycle. Such a setback is unheard of successful the company's SoC squad and is being attributed to respective layoffs and lawsuits that the radical successful presently contending with.
The Apple iPhone 14 Pro's A16 Bionic SoC uses a 5-core GPU that is not excessively antithetic from the 1 we've antecedently seen with the A15 Bionic successful the iPhone 13 Pro. The caller A16 5-core GPU comes with accrued representation bandwidth owing to LPDDR5 representation and is fabbed connected a TSMC 4 nm process. However, Apple seemingly had adjacent bigger plans for the iPhone 14 Pro's GPU going beyond conscionable bandwidth and ratio improvements.
According to a study by The Information, Apple engineers were primitively readying a "generational leap" for the iPhone 14 Pro's graphics processor. This included features specified arsenic enactment for hardware-accelerated ray tracing. ARM chips person already begun offering this feature. For instance, ARM's Immortalis-G715 and Qualcomm's Adreno 740 successful the Snapdragon 8 Gen 2 enactment autochthonal hardware-accelerated ray tracing.
However, Apple recovered a flaw successful the plan precocious into the improvement rhythm that forced the Cupertino-giant to revert backmost to the A15 Bionic's GPU plan with insignificant changes. Apparently, the prototypes drew much powerfulness than expected successful bundle simulations. This could person had atrocious implications for artillery beingness and thermals, according to sources with first-hand cognition of the matter.
The Information notes that specified a snafu has been "unprecedented" successful the group's past arsenic Apple mostly ensures important gains gen-on-gen. Consequently, Apple restructured its GPU squad and moved immoderate managers, including removal of important radical who person contributed to the company's mobile SoC dominance.
The work further notes that Apple's SoC squad had to contend with nonaccomplishment of endowment successful caller years to competing silicon companies, interpersonal feuds, and lawsuits with spot startups.
In 2019, 3 of Apple's engineers had moved connected to co-found Nuvia, which was acquired by Qualcomm successful 2021 for US$1.4 cardinal overmuch to the consternation of ARM. Earlier this year, Apple filed a lawsuit against a California-based "stealth" startup Rivos Inc. for "poaching" 40 of its engineers, 2 of them with gigabytes of confidential Apple SoC designs and commercialized secrets.
